comment What's the easiest way to access pure raw data (without demosaicing)?
I was just warning you: it's standard practice on SE to note if you're the developer, especially if it's not a free program. Otherwise someone might flag it as spam. (I won't do that, but since you're new here I thought it's fair to mention it.)

comment What's the easiest way to access pure raw data (without demosaicing)?
It's not free any more though, unfortunately, but it was a nice program when I tried it. It didn't seem to do anything more than dcraw though, other than adding a GUI. Are you one of the devs? If yes, you should make that clear in this post.

comment Which Nikon DSLRs have an autofocus motor in camera body?
A simple google search brings up the answer.

comment What is the difference between a linear and a circular polarizer?
The terminology used on photo sites is all messed up. What they call a "circular polarizer" is in fact a linear polarizer stacked with a circular polarizer. The second layer is not a de-polarizer as your post would suggest.

comment Will the petal-shaped “HB-45 II” lens hood work with my Nikkor 18-55mm?
The front of the lens you mention will rotate during focusing. This means that it is very likely to be incompatible with the flower-shaped hood. Even if it is mountable, the flower shaped hood is likely to cause vignetting at 18 mm when it gets rotated into an incorrect position.

comment Remove violet glowing effect
More specifically, this is lateral chromatic aberration: you can see that the outer (closer to the corner) edges are greenish and the inner ones are purplish. This type of chromatic aberration is easier to correct during postprocessing: RAW converters will typically have an option for it.

comment What personal safety precautions do I need to take while traveling with a camera in Scandinavia?
You just have to exercise some common sense. In Europe people will actually walk around on the street daily and take public transportation (unlike many "carland" parts of the US which don't even have sidewalks). Don't leave your camera on a bench and wander off in the park because the wrong kind of person might walk by and take it.

comment Why do two zoom lenses set to 200mm on the same camera produce different fields of view?
The keyword here to Google for is focus breathing (I'm surprised that no one mentioned it). It means that the angle of view changes (widens) as you focus closer. It is typical for lenses with very high zoom rations like the 18-200 mm. For a long lens like yours 3 m is close focusing. If you repeat the test and focus at infinity, you'll find that the difference is much smaller.

comment How can I make the most of entry level camera gear?
Stop reading sites where people discuss gear instead of pictures. Then you won't be unhappy about what you don't have ;-) What you have is still much more flexible (and gives better quality) than most new compacts. I used a Nikon D60 with a single 35 mm 1/1.8 lens for > 2 years and I was very happy with it. One of the things that gave me the biggest improvements was starting to shoot RAW and post-processing it. Also, instead of thinking about stuff you can't do (shoot small birds or do macro) focus on stuff you can do with your current setup. I tried some panoramas and time lapses.

comment Nikon 55-200mm or 50mm
Is this going to be your only lens? Or are you getting it together with a kit lens? If it will be your only lens, then the answer will necessarily have to be neither ... if not, it depends on what you like to do.

comment Does median blending / image stacking result in better or worse results than a long exposure?
@KartickVaddadi "But shouldn't the MEDIAN of 10 one-second exposures give less noise?" <-- If you consider the shot noise (Poisson), then taking the median will in fact result in higher noise than taking the mean. However, the median will effectively discard outliers, for example if a cosmic ray hit the sensor during exposure (not part of the short noise), while the mean won't. Some interesting reading on this here.
